Title: Laser oscillator
Inventor: HAMAGUCHI MASAHIRO
IPC: H01S3/03
Filed: 1990-03-08
Abstract: PURPOSE:To equalize the discharge intensity so as to enable the output of a stable laser beam by positioning a screening means at the part where the discharge intensity is strong viewed from the cross section of a discharge tube. CONSTITUTION:When the high frequency AC voltage from a high frequency power source 13 is applied between discharge electrodes 11a and 11b, the laser medium charged in the discharge tube 10 is excited, and laser oscillation occurs between a full reflecting mirror and a partial reflecting mirror, and one part of it is output as a laser beam through the partial reflecting mirror. At this time, a screening means 12 is provided, inside the discharge tube 10, to oppose the part where the opposite distance between the discharge electrodes 11a and 11b is near. Hereby, the discharge at the part where discharge intensity is strong is relaxed, and the it becomes the discharge being uniform in cross section of the discharge tube 10.

Title: Lubricating nozzle
Inventor: IDE MASAAKI
IPC: F16N7/34
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To hold sufficient strength even in high temp. oil by providing a nozzle orifice to the upper part of a plug element made of a fiber reinforced polyamide resin subjected to insert molding so that the protruding piece of an embedding part is embedded in the stepped flange part of a base part of the plug element. SOLUTION: A stepped flange part 2 is formed to the base part of a plug element and the nozzle orifices 4, 4 communicating with a hollow part are provided to the peripheral surface of the upper part of the plug element 1. Since the plug element 1 is composed of a fiber reinforced polyamide resin, the strength thereof is not lowered by high temp. oil and, since the plug element 1 is extremely light, it is hard to receive the effect of the vibration of an engine. Since the plug element 1 and an attaching plate 6 made of metal are integrated by insert molding through a rotor-shaped embedding part 8, the plug element 1 is rotated to prevent that the jet position of oil is shifted to generate lubrication inferiority.

Title: Heater tool structure and method and apparatus for thermocompression
Inventor: ITO ATSUSHI
IPC: B23K3/04
Filed: 1995-02-20
Abstract: PURPOSE: To make constant the bonding temperature over the entire thermocompression face of a heater tool by forming a pair of temperature control openings having volume increasing gradually from the central point of a plane facing the thermocompression plane at a heating part toward the opposite ends in the longitudinal direction of the heating part at a plurality of points in the thermocompressing direction. CONSTITUTION: A temperature control opening 45 is made in the plane 41e facing the thermocompression plane 41d of a heater tool 41 while being enlarged toward the opposite ends in the longitudinal direction of a heating part 41a. Consequently, the heating current path is limited toward the opposite ends in the longitudinal direction and the resistance is increased as compared with the central part thus increasing the Joule's heat. In other words, temperature at the opposite ends of the heating part 41a is elevated and sustained higher than the central part thus ensuring an averaged temperature distribution as a whole. With such structure, the bonding temperature can be sustained at a constant level over the entire thermocompression plane of the heater tool and the effective length can be lengthened correspondingly.

Title: Detection of welding start point
Inventor: KOGA EIJI
IPC: B23K9/127
Filed: 1983-03-29
Abstract: PURPOSE:To enable welding from the mid-way of a weld line by correcting the positional deviation of a welding start point in the weld line direction of two works intersecting orthogonally with each other to provide a reference plane and determining the point apart by a desired distance from the reference plane as the welding start point. CONSTITUTION:The tip of a torch T is lowered from a position P1 and when the tip comes to a position P2, the torch T and work W1 contact with each other. The torch T is then moved to a position P3 to correct the positional deviation in the Z-axis direction. When the torch T is moved left to P4, the torch T contacts with a work W2. The torch T is thereupon moved right to a welding start point P5 to correct the positional deviation in the X-axis direction. The positional deviation in the weld line direction is corrected at the position P6 in the same way as in the correction of the positional deviation in the Z-axis or X-axis direction, by which the end face of the work W2 is determined as the reference plane in the weld line direction. The point apart by a desired distance L from this reference plane R is determined as a welding start point PS.

Title: Excavation rod
Inventor: FUKUDA ATSUO
IPC: E21B17/00
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To contrive the improvement of a function by making the cross section outer shape of a shaft part elliptical or oblong in the excavation rod of an execution machine making the shaft part the transmission part of rotary force. SOLUTION: The traverse cross section outer shape of an excavation rod 1 is formed elliptical or oblong, and in the case where it is gripped by a chuck mechanism, slipping is prevented. Since the rotary force of a motor is surely transmitted and large chucking force is not needed, the deformation of the rod 1 is prevented. Next, since the traverse cross section outer shape of the rod 1 is nearly circular, a slurry-like matter is difficult to adhere to the surface, even when it is adhered, the failure of the execution machine caused by leaving an adhesive matter after cleaning is prevented because cleaning and removal by the conventional cleaning device are easy. Thereby idling at a part such as the chuck mechanism is prevented to surely transmit rotary force, the damage of the rod 1 can be prevented, and the adhesion of the slurry-like matter can be suppressed.
